Watlow EFit SCR Power Controller

Easy to integrate and commission, yet highly cost effective, the EFit power

controller provides no compromise control for resistive and infrared heating

elements.

Description

Uncompromising process performance in a cost effective format

Easy to integrate and commission, yet highly cost effective, the EFit SCR

(Silicon Controlled Rectifier) Power Controller provides no compromise

control for resistive and infrared heating elements. Ideal for all heating

applications and fully compliant to international quality, immunity, and

emissions standards, Efit power controller achieves outstanding stable, 

precise control in the most demanding industrial environments, even

when cabinet space is at a premium.

The perfect fit for simple heating applications

Some Industrial processes such as heat treatment require precise temperatures

in order to comply with regulations and it is imperative that the workpiece

temperature is kept within specific limits. This can be difficult to achieve in

industrial plants where the operation of large machinery can cause fluctuations

in the voltage supply. In the case of resistive heaters a variation of 10% in the

supply voltage will generate a 20% variation in the power to the load, resulting

in undesirable temperature fluctuations. EFit SCR controller contains built in

compensation that continues to apply stable power with better than ±2% linearity

at the boundaries of the load, even during fluctuations in the supply. The result is

a reliable, repeatable heating process and high quality end products compliant to

demanding heat treatment standards.

Connect Easily

Straightforward connection and commissioning, combined with a compact format

to maximise use of cabinet space makes EFit controller the perfect fit for power

control in both new and retrofit applications.

Easy Installation

• Nothing to configure — plug and play

• Nothing to fix — just clip onto DIN rail

• Minimal connection — pre-wireable plug in connectors

Easy Integration

• Compact dimensions reduce cabinet costs

• Integrates worldwide — global standard approvals and international voltages

• Consistent form factor — same height and depth across the range

• Ideal form and fit drop in replacement for EurothermTE10A

Improve Processes

Designed to give a fast stable response even in heavy industrial environments,

EFit SCR power controller will enable you to run continuously optimized heating

processes with minimum down time. This faster throughput improves OEE

(Overall Equipment Effectiveness), helping you achieve your KPIs

(Key Performance Indicators).

Increase throughput

• Maximise utilisation of plant equipment thanks to fast stable control response

Reduce down time

• Reliably operates in heavy industrial conditions — high immunity to electromagnetic disturbances

• Robust — operates in high temperature, humidity and altitude environments

Control Precisely

EFit SCR controller offers built in power stabilization and a variety of firing modes 

for different types of load, which lead to energy savings and higher quality end

products when compared to more basic power controllers.

Reduce hidden energy costs

• No wasted energy — built in compensation provides stable power control even

during power fluctuations, eliminating unexpected changes in heater temperature

• Better power factor— save hidden energy costs with dedicated firing modes for

each type of load, including a variety of burst modes that provide an efficient

alternative to Phase Angle, such as advanced single cycle firing to reduce flicker

in short-wave infrared heaters

Consistently high quality end products that comply to standards

• No scrap or rework – linearity better than ±2% of range, accurately controls

heaters and maintains the correct load temperature

Standardise Globally

EFit power controllers offer peace of mind for installers working in a global

environment where industry regulations form an essential part of the engineering

supply chain.

• Conformity to cUL directive (Canada and USA)

• CCC exempt: product not listed in catalogue of products subject to compulsory

certification

• China RoHS

• CE compliance to power controller product standards
